EDGAR WEBSTER SUMMERS, OF PITTSBURG, AND CHARLES H. CLARK, OF GRAFTON. PENNSYLVANIA.

RAILWAY-GAR.

To all whom it may concern:

Be it known that we, EDGAR WEBSTER SUM- MERS, a citizen of the United States, residing in Pittsburg, and CHARLES H. CLARK, a citizen of the United States, residing in Crafton, both being in the county of Allegheny and State of Pennsylvania, have invented a Railway-Car, of which the following description, in connection with the accompanying drawings, is a specification, in which like marks refer to the same parts throughout.

The objects of this invention are to combine as many functions in each piece as possible, thus reducing the number of pieces and connections; to make the side and end supporting members in the form of plate girders, they being also the side walls of the car in which wear and damage from shifting loads, and tugging and bufling stresses, are cared for by thicker sheets near the floor line than are used higher up; to reduce the riveting by combining connections; to simplify the top chord of the side girders by flanging the upper sheet at its upper edge, or by inserting a separate piece on the same line of rivets as the roof sheets; to provide against leaks by having no holes in the plane of the roof to the inside of the car; to secure clear head room by placing the carlines outside of the roof; to simplify the design by forming the carlines on standing flanges of the roof sheets, making the carlines so formed deeper at the center than at the ends to take care of the roof load; to provide connections for the running boards to the carlines without puncturing the roof and in like manner to secure guard rods on the roof.

The above is illustrated in the accompanying drawings in which:

Figure 1 is a vertical longitudinal section from the end of the car to a position near the center, taken in the line 11, Fig. 2. Fig. 2 is a vertical transverse section, the left side of which is on the line LL, Fig. 1 and the right side of which is on the line RR in Fig. 1. Fig. 3 is a perspective view of a section of the roof and upper portion of the sides of the car, and also illustrates two forms of connecting the roof to the side girders.

In the figures we show, the side girder with its heavy bottom chord section, 1; its thick intermediate section, 2; its thin upper section, 3 the top flange of the up er section, 3, being shown with an integra bent over 5 portion, 4, in one side of Fig. 3 and with a Specification of Letters Patent.

separate angle piece, 5, in the other side of Fig. 3 and with a U shaped piece, 6, in Fig. 2; the inner stifl'eners, 7, in Fig. 1 and the outer stiffeners, 8, in Fig. 3. The end is shown with the thick lower sheet, 9, and the thin upper sheet, 10, together with the corner connecting angle, 11.

We show the roof sheets, 12, with their integral vertical flanges, 13, and the U shaped cap piece, 14, in place over the vertical flanges, 13; the down turned flanges, 15, of the roof sheet, 12; the guard rod connecting piece, 16 the guard rod, 17; the running boards, 18 and their connecting clips, 19, and the inner connecting lugs, 20. We show the floor sheets, 21, with their downward bent connecting flanges, 22, and their upward bent end connecting flanges, 23; also the downward bent flanges, 24, of the end roof sheet connecting with upper end sheet 10 of the car.

The retaining walls, or the sides and ends of a boX car are well adapted to carry the vertical loads imposed upon the car provided that they be so constructed as to perform the functions of plate girders. For the purpose of web plates in such girders the side sheets could be comparatively thin; but the lower art of the girders are subjected to heavy forces due to tugging and buffin and to abrasion of loose or shifting loads in the car which require additional metal in the lower part of the girders; and we supply this, without additional framing members, by increasing the thickness of the lower web plates. By the use of web plates of diflferent thickness in the sides and ends of the car, as described above, it will be seen that the weight of the car is reduced below that of one in which the web plates are of uniform thickness from bottom to top, or that of one in which additional members are used to take care of the conditions enumerated.

To provide a top chord for the girder, the upper sheet of the web is turned over, or an additional member is used, as conditions may require, and as illustrated in the drawings. The usual vertical stiffeners are provided for the girder, and may be either inside or outside of the car; and serve also as supports for the web as a retaining wall.

For the purpose of transferring the floor load to the side girder and for simplicity of construction of the usual door opening the floor sheets, 21, are flanged downward and sheets, 1 and 2.

riveted through the flange, 22, to the side In as much as the lower side sheets above the floor are not continuous through the door opening, and in order to transmit the forces past the opening, we make the lower section, 1, of the side sheets preferably continuous from end to end of the car, fianging this member at the bottom only, and at its upper edge connecting it to the floor sheets, 21, and to the side sheets, 1 and 2, with a single row of rivets. This con struction is economical, as it requires only a single row of rivets to connect the side sheet, 2,which the door opening interruptswith the continuous side sheet, 1, and the floor sheets, 21, in such a manner as to leave the floor free of rivet heads and free to shovel over.

It has been found difficult to make and maintain a tight water-proof car roof. To accomplish this in a simple and economical manner, we use metallic roof sheets in sections extending crosswise of the car, preferably in continuous sheets from side to side. To splice the adjacent edges of the sections we flange them upward at their junction to form a standing seam. These upward flanged portions, 13, of the roof sheets, 12, are utilized to form the roof supporting carlines in addition to their function of turning the water from the joints. These carlines are made deep at the center and are increased in thickness in their upper portion in order to supply the necessary material to carry the roof load and they are decreased to a less depth at their ends for economy of material and for car clearance. It will be noted that we increase the metal in the upper portion of the carline, by the use of a cap plate, 14. This could be done, however, by turning one or both of the sheets over at the top of the standing seam, 13, either of which forms is usual for weather protection, but not as a carline. By making the carline an integral part of the roof sheets and by placing the carline on the outside of the roof, we utilize the material to perform several functions.

Reference has been made to the running board connections, 19, and 'the guard rod connections, 16 which are made without puncturing the roof and therefore can not cause leakage. For inner connections of the roof to the top chords of the side girders, lugs, 20, are used and are attached to the carlines by insertion between the standing flanges, 13, and have their connection to the carlines by the rivets through the cap plates, 14:.

This general form of roof construction provides a self supporting roof in which no rivet or other connecting holes are made through the roof to the inside of the car.

The downward turned flanges, 15, on the roof sheets, form. a drip and may also serve as a connection to the car sides as shown at the left of Fig. 3, or in Fig. 2. The end root sheet is :tlanged downward over the end wall of the car and serves as an end carline.

Many changes may be made in the details, from those herein described, without limiting the invention in which we claim:

1. In a box car, aside wall formed of a. metallic plate girder the web of which is spliced longitudinally of the car, the lower portion of the web having greater thickness than the up per portion, for the purpose set forth.

2. In a box car, a side wall formed of a metallic plate girder, the web of which is co1nposed of upper, intermediate and lower portions, the lower portion extending through continuously under a door opening, the intermediate and. lower portions having greater thickness than the upper portion, for the. pur pose set forth.

3. In a box car, a side w: ll in the form of av plate girder, the web of which is spliced at the floor line, and a down turned llange of the .tloor plates connected to the web by the rivets through the said splice, substantially as described.

1. In a box car, an end wall in the form of a plate girder the web of which is spliced in a horizontal line above the tloor, the lower por tion of the web having greater thickness than the upper portion, for the purpose set forth.

5. The combination in a covered car, of

metallic lloor plates having integral down turned flanges and. a plurality of metallic side sheets connected by a single row of rivets to said down turnedv tlanges of the tloor sheets.

6. In a metallic roof fora car, the combination with an outside carline formed on a standing seam of the roof sheets, of a running plank adjacent to the carline, and means for connecting the running plank to the carlino.

7. In a metallic roof for a car, an outside 1.

carline, a guard rod longitudinally of the car and means for connecting the guard rod to the carline.

8. In a covered car, the combination of a roof with a side girder having its upper chord formed of an integral bent-over portion of the side sheet.

9. In a covered car, an upper chord for a. side girder and a stiffener in the side. girder and means for connecting opposite sides of the stiffener to adjacent portions of the upper chord.
